'The rock' speaks on 'fast and furious 9'

In a new interview with Rolling Stone, Johnson finally opened up on the infamous feud between him and Diesel, confirming that the pair did not shoot any scenes together in the eighth installment of the franchise.
"Vin and I had a few discussions, including an important face-to-face in my trailer," he said. "And what I came to realize is that we have a fundamental difference in philosophies on how we approach moviemaking and collaborating. It took me some time, but I'm grateful for that clarity. Whether we work together again or not."
Back in 2016, while shooting Fate of the Furious, Johnson took to Instagram to call out one of his male costars for being an unprofessional "candy ass" on set. It of course didn't take long for TMZ to dig up the dirt and report that Johnson and Diesel had been at odds throughout the arduous production. The reason? Diesel's work ethic. According to TMZ, Diesel, a producer on the film, often held up production because he wouldn't come out of his trailer on time.
 When asked if he'd appear in the forthcoming Fast and Furious 9, Johnson said, "I'm not quite sure."
